The invention claimed is: 
     
       1. An armrest for being provided on a chair, the armrest comprising:
 a support member; 
 a movable member which includes a placing surface for supporting a limb of a seated person and is supported by the support member from below to be movable in a horizontal direction; and 
 a guide portion which indicates a position where the seated person touches when moving the movable member, wherein 
 the movable member includes an upper layer member and a lower layer member, 
 the lower layer member is supported by the support member from below, 
 the upper layer member is supported by the lower layer member from below to be movable in a horizontal direction, forms a finger-inserting space between itself and at least a part of the lower layer member, and is disposed at least partially facing the part of the lower layer member, 
 the armrest comprises a spacer member which separates a part of the lower layer member from a part of the upper layer member to form the finger-inserting space, 
 the lower layer member includes a base member, and 
 the spacer member is formed by a front step portion formed on a front end portion of the base member to support a front portion of the upper layer member and is provided in front of the finger-inserting space. 
 
     
     
       2. The armrest according to  claim 1 , comprising:
 a guide element which guides movement of the upper layer member in the horizontal direction with respect to the lower layer member, wherein 
 the guide element includes: 
 a guide groove which is provided on either one of the upper layer member and the lower layer member and is formed in a moving direction of the upper layer member; and 
 a guide protruding portion which is provided on the other of the upper layer member and the lower layer member and is slidably engaged with the guide groove. 
 
     
     
       3. The armrest according to  claim 1 , wherein
 the finger-inserting space penetrates from one side to the other side of the armrest in a width direction of the chair. 
 
     
     
       4. The armrest according to  claim 1 , wherein
 the base member forms an accommodating space opening upward, 
 the lower layer member includes
 a rotatable member which is fitted to the base member to be non-rotatable relative to the base member and is movable in a longitudinal direction of the chair within the accommodating space, and 
 a cover member which closes an upper open portion of the accommodating space, and 
 
 the cover member includes a front step cover portion which is formed in a stepped shape to be aligned with the front step portion. 
 
     
     
       5. The armrest according to  claim 4 , wherein
 the spacer member is formed by the front step portion and the front step cover portion. 
 
     
     
       6. The armrest according to  claim 5 , wherein
 the front step portion is changed upward in a stepped shape with respect to the accommodating space. 
 
     
     
       7. The armrest according to  claim 4 , wherein
 the front step portion is changed upward in a stepped shape with respect to the accommodating space. 
 
     
     
       8. A chair comprising the armrest according to  claim 1 .
